In the situation of varied water quality of influent, membrane permeate COD was all less than 20mg/L, NH〓-N was less than 1mg/L and turbidity was less than 1 NTU. Because the membrane surface formed gel layer in the filtration process, which reduced membrane pore size efficiently removed nosogenetic germ and virus and attained the demand of water quality standard in wastewater reuse.
在进水水质波动的情况下,膜出水COD值均小于20mg/L,NH〓-N小于1mg/L,浊度小于1NTU;由于在过滤过程中膜面形成了凝胶层,起到了减小膜孔径的作用,从而达到致病菌和病毒的有效去除,能够满足污水回用于杂用水时对水质的要求。

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.
